Almost before I finished typing up a blog about a disturbing report on the canine health risks posed by over-the-counter, spot-on pesticides[4], I saw the latest news about flea collars. Last week, the National Resource Defense Council[5]filed a lawsuit[6] alleging that 16 retailers and manufacturers—we’re talking the big guys here—failed to warn consumers about exposure to unsafe levels of known carcinogens and neurotoxins in violation of California anti-toxics laws.

Once again we’re being warned: “Just because it’s sold in stores doesn’t mean it’s safe.”

The NRDC’s groundbreaking Poison on Pets II[7] study found “that high levels of pesticide residue can remain on a dog’s or cat’s fur for weeks after a flea collar is put on an animal. Residue levels produced by some flea collars are so high that they pose a risk of cancer and damage to the neurological system of children up to 1,000 times higher than the EPA’s acceptable levels.” Something tells me the fact that this study identifies the risk to two-legged children will help the cause garner broader attention.

Meanwhile, it’s flea season across the nation and guardians need better, safer options right way. At Green Paws[8], the NRDC offers practical advice including a video (see below) on fighting fleas the old fashioned way, a product guide, and a wallet-sized primer on chemicals and herbal options.
